As an important test for General Relativity, the existence of a black
hole is always the focus of physicists and astronomers. Particularly in
these years, since a large number of advanced observational facilities
are put into use and the techniques improved, the search for the
evidence for black holes have made great progress, becoming one of
astronomical researching hotspots. In this paper,
... [Show full abstract] evidence for stellar
black holes and super-massive black holes in galactic nuclei is
reviewed, and the great advances in black hole astrophysics are also
introduced. Finally, we discuss some great developing projects and the
primary results of pursuing primordial black holes. The suggestions for
observations and the respect of astronomical evidence for black holes
are put forward.
